title: Changes of lateral soft tissue profile after surgical correction of mandibular prognathism.
abstract: The lateral soft tissue profile was recorded in 10 patients with slight to moderate degrees of mandibular prognathism, preoperatively, and 6 weeks after subcondylar sliding osteotomy had been performed. The recording method was mechanical. Only small and insignificant profile changes were found in the submandibular and occlusal plane regions as well as in the ramus region. The only significant change of profile was found in the mandibular body region, probably as a result of firm connection between soft tissue and underlying distally moved bone. The lack of significant profile change in the osteotomy region was in accordance with subjective observations and was probably due to local remodelling and adaptation processes. The facial width was thus found to be unaltered 6 weeks postoperatively.
